![]() ![]() ![]() The 60G gearbox requires only minor tunnel modifications to accept the new gearlever mechanism, whereas the 69G is a bulkier unit requiring the manufacture of a new gearbox tunnel. This is known as “flat shifting” as no clutch or lifting of the throttle is required during the gear change!įor 2wd YB cosworth powered cars, we usually recommend using a Quaife 60G 6 speed sequential gearbox for power outputs up to 450bhp, and its bigger brother the Quaife 69G for power outputs of 500bhp and above! Available with several gear ratio options, ratios can be chosen suitable for road and track day use, as well as ratios suitable for circuit or rally use. The result is a gearshift of near instant selection (typically 0.06 of a second) with the only driver requirement of pulling the gearstick. At this exact moment the ecu reduces engine load by a combination of fuel cut and ignition retard, whilst the driver keeps his foot firmly to the floor. In conjunction with a suitable ecu such as the AEM Infinity, rather than lifting slightly on the throttle, a strain gauge is added to the gear lever, indicating to the ecu when the driver is pulling the gearstick. This allows clutch less upshifts and speeds up gear changes to around 0.2 of a second. All that is required to change gear is to pull the gear lever and lift slightly on the throttle to reduce load on the dogs. The gears are engaged using a ring of dogs, machined in a manner that keeps the gear engaged under load. ![]() This type of gearbox features a gearstick that moves only forward or backward, in a “pull” to change up, “push” to change down format. The only recommended solution for these high output engines is to use a sequential dog engagement gearbox. In addition as power outputs go up, we start to experience gearbox failures such as stripped gears on high bhp cars, or damaged synchros due to forced “crunched” gearchanges. A traditional syncho gearbox struggles with this increased demand, often baulking or crunching, in an attempt to change gear quickly at high rpm. This results in gear changes that need to be made at both higher rpm’s and in a quicker time, so as to keep the turbo or cams “on song”. Often along with these higher rpm’s the power band becomes a little narrower, either due to the lairy nature of “race” cams or by the late spooling of large turbochargers. *Version 2 Update* We are now supplying the QKE8J Version 2 which has been updated with a revised shift mechanism which incorporates the ability to connect a pneumatic shift system directly to the gearbox from factory.Usually as we increase the power output of both turbo and N/A engines, the extra power is made at higher rpm’s. PLEASE NOTE: The Quaife QKE8J package includes the new transmission housing, gear lever and cable. Quaife ATB for standard driveshafts (QDF9U). Optional LED digital gear position indicator available. Retains stock EP3/FN2/DC5 clutch, diff, driveshafts and mounts. Ultra fast sequential gearshift with straight cut or helical close-ratio gears. Strengthened outer casing and five wider gears.Key technical features of the QKE8J five-speed Honda EP3/FN2/DC5 sequential gearkit include:. There is also the choice of a helical set for road and track day applications. Wide straight cut (spur) close-ratio gears minimise transmission losses and offer a choice of rally, race or drag race gearing. QKE8J re-uses the original EP3/FN2/DC5 bellhousing half of the transmission casing, enabling the retention of the Honda clutch, differential, driveshafts and mounting points. A compact, drum style sequential gearchange mechanism and an open face dog design ensure an ultra rapid, positive gear sequential shift. QKE8J features a replacement Quaife outer gearbox case incorporating an additional support bearing between 4th and 5th gear. Ideally suited to circuit racing, drag racing and rally use it’s designed as a direct replacement for the standard six-speed H-pattern Honda transmission. QKE8J is a 5-speed sequential gearkit for the EP3 and FN2 versions of the Honda Civic Type R as well as the DC5 Integra / RSX. ![]() This an oversize item that will require freight shipping. ![]()
